To all 'whom t may concern.'

Be itknown that we, PETER ZUMB'ERG 'and JOSEPH SARDIN, citizens of the UnitedStates and Russia, respectively, residing at Detroit, county of 'Wayne, State ot Michigan, have inventeda certain-new and useful Improvement in Oil-Presses, and declare theollowing to be a full, clear, and exact description oi" the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this speciication. y

Our invention relates to presses and an object or' our improvements is to provide an improved apparatus for pressing the oil from various kinds of seed.

le secure this object in the device illusltrated in the accompanying` drawings in which;

Figure 1 is an elevation, partly in section, of an apparatus embodying our invention. Fig. 2 is a plan view of the same. l

Fig. 3 is a detail plan view, partly in section, on the line C-k-C Fig. 1.

Fig. 4f is a detail section on the line D-D Fig. 1.

Fig. 5 is a detail section showing the construction of the hydraulic cylinder and ram and the carrying plate on the latter.

Fig. 6 is an elevation of the outer envelop of the container for the seed to be pressed.

Fig. 7 is the inner envelop of the same.

a is a tank Jfor containing liquid, b b are cylinders having pistons operating therein and connecting rods pivoted to cranks on a crank shaft a3 resting in bearings on standards in the tank at, a2 is a pulley by which the crank shaft a3 may be rotated.

l/Ve have represented the cylinders of the pumps generally without illustrating the valves operative therewith inasmuch as these are -conventional constructions and can easily be supplied by a mechanic. c is a common' delivery pipe for the cylinders Z) I), and d is a valve in the pipe c adapted to be opened to put the interior ,of said pipe into communication with the interior of the tank a. e is a lever by which the valve Z may be opened.

g is a hydraulic cylinder having a plunger h therein. The pipe c is provided with a pressure gage between the pump and the hydraulic cylinder as shown. The delivery pipe a opens into the cylinder g below lthe plunger L. m isa carrying lplate onthe'uppeil 'end ofthe plunger isthebase plate an'd ji'anupper plate united by 'guidebars Ict/v to forni a'franie. IThelhydrauliccyline der g is secured to the lbase Aplate of `said frame and opens therethrough. m a carrier plate normally resting'upo'n theibase plate i of the frame and secured to the up-V per end of the plunger L. n is a cylindrical projection extending downward from the center of the plate The projection 11, is axially in line with the plunger h. p and p2 are symmetrical halves of a' rcylinder p. These halves are provided with lugs p3 eX- tending outward forming adjacent edges and having registering cylindrical openings therein. 794 are vertical slots through the walls of the cylinder p. Q g2 are the two symmetrical halves of an outer envelop cylinder having lugs gt upon two adjacent edges which are adapted to be secured together by bolts and nuts. There are registerings lugs g3 at the other adjacent edges of the parts g Q2 and these parts are cut away to form openings having parallel horizontal walls as shown at g5A in Fig. 6.

The container for the seed is formedby putting two halves of the cylinder p together, putting the outer envelop g around the cylinder p and passing a pin or bolt m through the registering openings of the lugs g3 and p3. The latter of which lugs are interposed between the lugs g3 in the openings The lugs g4 are then secured together by bolts and nuts.

The seed container thus formed is placed upon the carrier plate m, as shown in Fig. l, the seed placed within the hollow of the inner cylinder j? and the hydraulic pumps are set in operation forcing the plunger 7L upward carrying the carrier plate m and compressing the seed by means of the projection a passing into the cylinder 79, the oil running out through slots p4 in the latter cylinder and passing through the openings Q5 falling upon the carrier plate fm. which is hollowed out at its outer surface and running oii' in a spout m2.

What we claim is:

l. In an oil press, the combination of an inner envelop having vertically extending slots through its wall, an outer envelop having horizontal openings through its walls,

and means for securing said outer envelop around said inner envelop.

2. In an oil press, the combination of an Patented sept..3,11918.

g Lavage?? inner envelop formed in two halves and edges and having horizontal openings in its having vertical slots through its Walls7 an walls, saidouter envelop being adapted to 15 outer envelop formed in two halves having pass around said inner envelop with the horizontal openings in its walls, the outer apertures through its lugs registering with 5 envelop being adapted to have its two parts the apertures through the lugs of the inner rigidly; secured together around said inner envelop, a bolt passing through the aperenvelop. tures in said lugs, and means for securing 20 3. In an oil press, thev combination of an the edges of the outer envelop opposite said inner envelop having two parts having lugs lugs rigidly together.

1@ with registering apertures therethrough at In testimony whereof we sign this spec adjacent edges and having vertical slots iication. through its walls, an outer envelop having PETER ZUMBERG. lugs with registering apertures at adjacent JOSEPH SARDIN.

opies o this patent may be obtained for five cents each', by addressing the Commissioner ot Patents.
